11. Ways to improve f+-/f00

James Frederick Libby (BELLE (BELLE II Experiment))

To overcome the current used value affected by large isospin-breaking uncertainty, and to account for any c.m.-energy dependence

17. Slow-pion efficiency

The slow-pion efficiency and its associated systematic uncertainty is currently the major limitation of the exclusive measurement with B->D*(D0 pi_s) l nu decays. Can we improve the slow-pion efficiency? Can we reduce its systematic uncertainty?

18. Lepton ID challenges

A key ingredient of SL measurements are LID efficiencies, their corrections and systematic uncertainties. The talk review on this topic with particular focus on current limitations and modelling of LID uncertainty correlations.
